.action is easily effected and wherein the brush is provided with a plunger to open up passages within these vessels at the same time the brush is being used for scrubbing action upon the vessel. It is another object of the present invention to-provide'a plunger brush construction wherein aplurality of individual scrubbing fingers can be readily provided which will have Weighted ends to facilitate the flinging and scrubbing action of these fingers and to impart to the surface being cleaned heavy scrubbing action and wherein cleaning action can be effected'under flanges of the various vessels to thereby render such vessels more sanitary by having them cleaned under such flanges. '-It is another object of the invention to provide a plunger brush which has a plurality of weighted fingers and wherein two circular rows of these weight fingers are provided by a separation of alternate fingers cut from a common plane and held by a cylindrical rubber band toprovide the two rows of fingers concentric with one another. a

It is -a further object of the present invention to provide an attachment for standard water closet plungers which can be extended downwardly overthe handle and upon the conica1 top face of such plunger and in such a manner as to provide concentric rows of fingers over the plunger body and outwardly thereof. Other objects of the present invention are to provide a plunger brush of the type above set forth which is of simple construction, inexpensive to manufacture, has a minimum number of parts, compact, easy to manipulate, of long life and efficient in erati n:

h I for abetterunderstanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a top plan view of the plunger brush constructed according to one form of the invention.

Fig. 2 is an elevational view of the brush.

fled form of the invention where the brush fingers are assembledupon a standard plunger and as an attachment therefor.

Fig. 5 is a fragmentary sectional view of the form of the invention shown in Fig. 4 assembled on a plunger.

Fig. 6 is an illustrative fragmentary perspective view showing the manner in which the rows of fingers are maintained in spaced relationship by the circular rubber ring.

Referring now particularly to Figs. 1, 2 and 3, It) represents a main body of flexible material having a threaded top opening ll into which is fitted an operating stick or handle l2 threaded at its end in the usual manner to engage with the threaded opening H. This bodyv ID has a plurality of weighted fingers l3 extending laterally therefrom and having respectively weighted enlargements I4 for effecting a heavy scrubbing action. These fingers may extend directly radially outwardly or may be angled with respect to a radial line nearing a. tangential position as shown in Fig. 1. The respective fingers are downwardly and outwardly curved and are adapted to slide outwardly or expand under centrifugal action resulting from a twisting or rotation of the operating handle l2. In this manner the fingers are flung outwardly and can reach under the flange of vesselsbeing cleaned so as to do a thorough cleaning job upon such vessels.

1 In order to provide two concentric rows of fingers and to have one row of fingers extending downwardly to a different elevation from the other row of fingers, alternate fingers are depressed and a circular flexible band I6 is disposed between the rows of fingers. 'The inner row or depressed fingers are indicated respectively by numeral I3. These fingers are thus formed of the same shape as the other fingers and have the same weighted end enlargements. Secured to the body 10 and within the inner row of fingers is a plunger cup I! having the usual heavy outer peripheral flange l8 and by means of a rivet l9 extending downwardly from the bottom of the threaded opening H and through the topOfthe cup". V

Referring now particularly to Figs. 4, 5 and 6, there is shown a modified form of the invention wherein the fingers are supplied to a standard plunger cup I9 by means of an attachment 2| having two rows of fingers extending outwardly and downwardly as with the preceding form of the invention. The outer fingers are indicated at [3" and the inner fingers are indicated at l3. The attachment 2! has a top hole 22 for receiving an upstanding attaching portion 23 of the plunger cup l9 and to which operating handle I 2 is attached. The rows of fingers lie in the same manner as with the first form of the invention externally of the plunger cup and are separated or expanded when plunger action is effected with the cup. The attachment 2| may utilize the same flexible band or ring It for separating the rows of fingers; ZT i I f I i In operatiomthe brush is given a swirling action and the fingers will be extended and will wipe effectively upon the surface being cleaned. Due

to the weighted end enlargements, a.- -brisk' andheavy rubbing action is effected upon the surface of the vessel being cleaned. To assemble theattachment 2! upon the plunger cap l9- and to retain the same in a rigid position thereupon, the opening 22 is slightly smaller in diameter than the upstanding portion 23 of the cap whereby there is little chance forthe attachment 2| to climb upwardly! upon the: upstanding portion. 23. .-.':It w'ill be apparent that the brush can. be used with but a single row of fingers weighted the same'm'anner as. above described and circumferenti'ally spacedwithrespect'to one another; a slight distance in order to allow for a free swinging. movement of the fingers.

It will also be apparent that there has been provided a plunger-brush formed of weighted flexible fingers adapted to act upon. a. surface. to be cleaned with a scrubbing action and with heavy force resulting from the weighted ends.

It will be furtherapparent that'the action of these fingers is effected by a twirling, twisting or rotating of the operating handle. The fingers may beprovidedwi th a-roughened surface to-providemo re effective scrubbing action.

While various changes may be made in the detailconstruction, it shall be apparent that such changes will be within the spirit and scope of the present invention as defined by the appended claims;

'- What is claimed is:

1. A brush comprising a body portion, a plurality of circumferentially arranged downwardly and outwardly curved weighted fingers connected tothe body portion, alternate fingers being depressed whereby to provide inner and outer rows of fingers and means extending between the depressed-fingersand the fi'ngers which are not depressed to retain the depressed fingers in place to provide the inner row, an operating handle and means securing the body portion to the operating handle whereby upon rotation of the operating handle the weightedfingers will be flung outwardly under centrifugal action to efiect a cleaning of the'surface of the vessel being cleaned.

' 2'. A brush comprising a body portion having acentral threaded opening, an operating handle threadedlyconnected into the threaded opening,

a plurality'of outwardly and downwardly curved weighted finger portions circumferentially arranged-andconnected about the body portion and operable forjcleaning action upon a twisting or rotation ofthe handle, said weightedfingers being arranged in concentric inner and outer rows, alternate fingers providing an inner circumferential row, means extending between outer and inner fingers for maintaining the inner and outer fingers spaced from one another and in circumferential relationship.

3.
